Henckelia longisepala (Gesneriaceae), a new record for Vietnam

Abstract

Henckelia longisepala (H.W.Li) D.J.Middleton & Mich.Möller is reported from Lai Chau and Nghe An provinces of Vietnam as a new national record of the species. An amended morphological description and
photographic illustrations are provided. The distribution of H. longisepala is discussed with an emphasis on the
floristic regions inhabited by this species. A specimen at
KUN is selected for a second-step lectotypification. Two floral morphologies were found in H. longisepala that differ in the length of the pistil and its significance is
discussed here.
